Tens of thousands of people have been taken into custody over suspected links to Gulen since 2016 while over 100,000 -- including teachers, police officers, and judges -- have been sacked or suspended from the public sector.

Turkish Justice Minister Abdulhamit Gul said last month that 31,088 people have been convicted or jailed over suspected Gulen links.
